ODOKIN, 85 



formed, which may be distilled over without alteration. It is 

 very soluble in water, and when exposed to the air absorbs oxy- 

 gen, and is converted into sulphate. Acids decompose it with the 

 evolution of sulphurous acid gas. 



3. Nitrate of odorin may be distilled over ; but it undergoes 

 a partial alteration during the process. What comes over is 

 a mixture of nitrate and nitrite of odorin, together with an em- 

 pyreumatic oil. The residue in the retort, besides undecomposed 

 salt, consists of an extractive matter and a resin soluble in po- 

 tash. 



4. Carbonate of odorin is a volatile oiL 



5. Borate and benzoate of odorin when exposed to the air, 

 let go by far the greatest part of their base ; but retain a small 

 portion of it with considerable force. 



6. Unverdorben did not succeed in his attempts to combine 

 odorin with arsenious acid. 



7. Muriate of odorin may be formed by causing the base to 

 absorb the acid in the gaseous state. It is a colourless oil, which 

 does not become solid though cooled down to 13. It may be 

 distilled over without decomposition, and is very soluble in water. 



When a current of chlorine is passed through odorin, decom- 

 position takes place, muriate of odorin is formed, but the great- 

 est part of the liquid is converted into a thick yellow magma. 

 About two-thirds of the odorin is converted into this matter, 

 while the remaining third becomes muriate. The yellow mag- 

 ma is partly soluble in potash, from which it is precipitated by acids 

 in the state of a yellowish-brown powder. The portion insoluble 

 in potash is a resinous-looking substance, fusible and soluble in 

 concentrated sulphuric acid. 



Muriate of odorin has a brownish-yellow colour, and is solu- 

 ble in water, alcohol, and ether. When distilled odorin passes 

 over, and a supersalt remains in the retort. 



8. When iodine is added to odorin, a powder is formed, hav- 

 ing a brown colour, and insoluble. There is formed at the same 

 time an extractive-looking substance, soluble in ether, and pre- 

 cipitated by the salts of lead and silver. 



9. The double salts of odorin have more fixity and a stronger 

 resemblance to the common class of salts than the simple salts. 



Sulphate of copper is dissolved by odorin, and the solution 

 has an intense blue colour. A subsalt of sulphate of copper re-
